I have a road bike and it's making this intermittent "ping" noise. It sounds like a spoke is hitting the fork, but I have checked that and it's not the case. Also I would assume that if that were the case the noise would be more regular (every rotation). Could it be the wheel bearings starting to go to hell?

Yes. Try taking the wheel off and spinning the axle by hand. If that feels at all rough, you should open it up and inspect.

Other things could be a loose spoke or maybe even a loose reflector. Maybe check the rim for any signs of cracks at the spoke holes or the seam where it was joined (this is opposite the valve hole and is where the rim was bent into a circle and joined together.)

It could be the spokes stress relieving if it is a recently trued or built wheel. If this is the case; the wheel should be trued, retensioned, stress relieved, trued, repeat last two until truing is no longer required.
